These are 45 patients, who received treatment in surgical department of head and neck tumors in Blokhin National Medical Research Center of Oncology between 1994 and 2020. Patient observation time averaged 30.0 ± 32.3 months (from 0.7 to 117.4 months, median 12.0 months). We divided patients into 3 groups depending on treatment methods. Group 1 consisted of patients who received combined or complex treatment (33.3 %, n = 15). Treatment for first group patients involved subtotal, lateral temporal bone resection or incomplete lateral resection and postoperative radiation therapy on the area of primary tumor and regional metastasis zone (total focal dose from 60 Gy). In the case of complex treatment, radiation therapy had carried out against background cisplatin introduction. The second group consisted of patients who received only surgical treatment (40.0 %, n = 18). Temporal bone resections were not performed for patients of the third group (26.7 %, n = 12). Treatment for patients of the third group involved one of the treatment methods: cryodestruction, laser destruction, photodynamic therapy, radiotherapy or chemoradiation treatment.</p><p><bold>Results.</bold> Five-year survival without signs of progression in a group of patients with locally advanced of the ear skin cancer, who received combined or complex treatment was 73.8 ± 13.1. Median progression-free survival not achieved. In the surgical treatment group 5 year progression-free survival was 40.4 ± 13.0, median was 34.1 months. In a group of patients who did not undergo temporal bone resection (3rd group) median progression-free survival was 4.5 months. Group differences are statistically significant (p &lt;0.05). The most significant adverse prognosis factors that reduce overall survival for patients with locally advanced external ear skin cancer are positive histological margin (p = 0.0001, hazard ratio (HR) = 10.611, 95 % confidence interval (CI) 3.058-36.820), signs of destruction branch of the lower jaw/ zygomatic bone (p = 0.027, HR = 4.65, 95 % CI 1.193-18.116). Facial paralysis is the most unfavorable prognosis factor, reducing tumor-specific survival in patients with locally advanced outer ear skin cancer (p = 0.0001, HR = 19.146, 95 % CI 4.056-90.388).</p><p><bold>Conclusion.</bold> Combined/complex treatment of patients with locally advanced ear skin cancer (surgery with postoperative radiotherapy/chemoradiotherapy) provides better long-term results compared to other treatment options.</p></abstract><trans-abstract xml:lang="ru"><p><bold>Цель исследования</bold> - изучение отдаленных результатов лечения больных местно-распространенным раком кожи наружного уха.</p><p><bold>Материалы и методы.</bold> Настоящее исследование основано на ретро- и проспективном анализе данных комплексного обследования и лечения 45 пациентов с местно-распространенным раком кожи наружного уха, получавших лечение с 1994 по 2020 г. в условиях хирургического отделения опухолей головы и шеи ФГБУ «Национальный медицинский исследовательский центр онкологии им. Н.Н. Блохина» Минздрава России. Время наблюдения за больными составило в среднем 30,0 ± 32,3 мес (от 0,7 до 117,4 мес, медиана 12,0 мес). Все пациенты были разделены на 3 группы в зависимости от метода лечения. Первую группу составили больные, получившие комбинированное/комплексное лечение (33,3 %, n = 15), которое предполагало операцию в объеме латеральной либо субтотальной резекции височной кости либо неполной латеральной резекции с последующей лучевой терапией на область первичной опухоли и зоны регионарного метастазирования (суммарная очаговая доза от 60 Гр). В случае комплексного лечения лучевая терапия проводилась на фоне введения цисплатина. Пациенты, получившие только хирургическое лечение, отнесены ко 2-й группе (40,0 %, n = 18). В 3-ю группу (26,7 %, n = 12) были включены больные, которым не выполнялась резекция височной кости. Лечение предполагало применение одного из 5 методов: криодеструкции, лазерной деструкции, фотодинамической, лучевой либо химиолучевой терапии.</p><p><bold>Результаты.</bold> Пятилетняя выживаемость без признаков прогрессирования в группе больных местно-распространенным раком кожи наружного уха, получивших комбинированное/комплексное лечение, составила 73,8 ± 13,1 % (медиана не достигнута), в группе хирургического лечения - 40,4 ± 13,0 % (медиана 34,1 мес), в 3-й группе (резекция височной кости не выполнялась) медиана выживаемости составила 4,5 мес. Различия в группах статистически достоверны (р &lt;0,05). Наиболее значимыми факторами неблагоприятного прогноза являются положительный гистологический край резекции (р = 0,0001, отношение рисков (ОР) 10,611, 95 % доверительный интервал (ДИ) 3,058-36,820 - для общей выживаемости), признаки костной деструкции ветви нижней челюсти/скуловой кости (р = 0,027, ОР 4,65, 95 % ДИ 1,193-18,116 - для общей выживаемости), поражение лицевого нерва (р = 0,0001, ОР 19,146, 95 % ДИ 4,056-90,388 - для опухоль-специфической выживаемости). Заключение. Комбинированное/комплексное лечение больных местно-распространенным раком кожи наружного уха (операция с последующей лучевой/химиолучевой терапией) обеспечивает лучшие отдаленные результаты в сравнении с другими вариантами лечения.</p></trans-abstract><kwd-group xml:lang="en"><kwd>outer ear skin cancer</kwd><kwd>temporal bone resection</kwd><kwd>long-term treatment results</kwd></kwd-group><kwd-group xml:lang="ru"><kwd>рак кожи наружного уха</kwd><kwd>резекция височной кости</kwd><kwd>отдаленные результаты лечения</kwd></kwd-group><funding-group/></article-meta></front><body></body><back><ref-list><ref id="B1"><label>1.</label><mixed-citation>Bacciu A., Clemente I.A., Piccirillo E. et al.
